GitHub will now create a branch and a commit for your changes (forking the repository first if this is your first contribution) and it will also display a preview of your changes: If everything is correct, click on the Create pull request button.

GitHub will display a new page where you can do some last-minute changes to your pull request before creating it. For simple contributions, you can safely ignore these options and just click on the Create pull request button again.

Congratulations! You just created a pull request to the official Drupal Commerce documentation! The community will now review your pull request and (possibly) suggest tweaks.

But if you want to contribute heavily, we recommend you doing a local setup of the documentation.
